Essex found that Motorola had violated four Microsoft patents. But Torvalds helped convince the Administrative Law Judge that the patent was invalid. Microsoft says that Motorola patent violated one of its own, known as the 352 patent. This dealt with the storing filenames with lots of characters in old filesystems such as the Windows FAT. Mobile phone makers use this type of technology so that their devices interoperate with other operating systems, including Windows. Torvalds said that Motorola had found the posting of his about long filenames used in a compatible manner with short file names - and that it predated the Microsoft patent by three years.
